ios - Google Analytics 3.12 在 iOS 上崩溃

Question

我是 iOS 开发新手，我的 iOS 应用程序(由供应商开发)崩溃了。我学会了阅读日志，这就是我所看到的:

2015-06-15 19:00:51.628 my_app[2540:113596] WARNING: GoogleAnalytics 3.12 void GAIUncaughtExceptionHandler(NSException *) (GAIUncaughtExceptionHandler.m:48): Uncaught exception: *** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array
2015-06-15 19:00:51.636 my_app[2540:113791] INFO: GoogleAnalytics 3.12 -[GAIAnalyticsPropertiesStore propertyRecordForTrackingId:] (GAIAnalyticsPropertiesStore.m:464): Record for tracking id my_tracking_id not found
2015-06-15 19:00:51.640 my_app[2540:113791] VERBOSE: GoogleAnalytics 3.12 -[GAIBatchingDispatcher persist:] 

我想知道是 Google Analytics(分析)导致了崩溃还是其他原因导致了崩溃。 API 调用正常，应用程序的其他部分也工作正常。

刚刚遇到了类似的问题，并得出结论，不是 Google Analytics 导致了崩溃。 Google Analytics(分析)只是为了报告目的而绕开另一次崩溃。

如果您在 App Delegate 的 didFinishLaunchingWithOptions:(或其他位置)中更改以下设置，则崩溃将在 XCode 控制台中显示为正常错误:


GAI *gai = [GAI 共享实例];
gai.trackUncaughtExceptions = NO；
